IMPROVEMENT m cHURNs.

l l 'Lillie Schedule referredto in these Letters `Patent and making part of the saine,-

To clima/ 1] concern.- n A 4 Beit known that LMlLil-ONJONES WIKOFF, of

Stouts Post-Oilicmin the county of Adams and State of Ohio, have invented a new and useful Improvement in Ohurns; 'and Ido hereby declarethat the following is a full, clear, and exact `description thereof, which will-enable others skilled `in the art to make and use the same, reference heingvhadto the accompanying drawing forming part of this specification.

This-invention relatesto a new and improved arf `rangement of the shaft and arms of a churn-dasher,

for introducing ariinto` the cream from the space in thecase above the'cream, all as hereinafter more fully Figure -2`is a plan view of thel daslier. A is the case or vessel, which may be of any ap- It is made hollow andextends above the top or lid C, which is,removable`,`and in suppoited in `a trans- "verse bar, D, l'et intolnotches in the upper en d of the case, so that it `may be readily taken out to remove the dasher when required, for cleaning or otherr purposes. l f l E represents the arms of the dasher.y

They are also made hollow with large bell-mouths,

"F, opening at the endsfat the receding sides, where a vacuum is created in the cream by the enlarged ends of the arms moving rapidly through it; i

These hollowanns receive the air from a hollow shaft, which has an opening at the upper end for the admission of i the air from the exterior.-

Itv also has an opening at G below the lid, and a band, H, at one sidefor directing the air into it.

It is also provided with a tubular valve, I, for closing or opening` the passage G, for admitting or stopping the air thereat by lowering the said tubular valve so that thelcylindricalfpart, K, falls below the orifice `or 'slightly less. .are raised, when the cold air is drawn in by the re- G, or raising it to cause the said part K to cover the orifice. l

M is an'air-pipe, having the cap N attachedtoa slide to close its aperture.

The shaft' B of the dasher projects through a stuifing-box in the bottom of the case, and is turned by gear-wheels, P Q, connecting with the large driving- Wheel R, attached to a stud on the side of the case,

but it may be operated by wheels applied to the top of the case, and gearing with the top of the shaft.

The mode of operation is as follows:

The top caps, M and N, arefrmly closed and the valve-slide R graduated so as lto force a continuous current of air from the upper part of the churn through `the cream. The -iction of the dasherrarms against the liquid raises its temperature, while the aeration, which it is constantly receiving through Band E E, maintains an equalization thereof throughout the mass. p This desideratum is obtained by a rapid and ythorough intel-mixture of air and milk, whereby the whole rises inv temperature evenly and simultaneously. i

Under these circumstances the conditions required for the formation of butter are obtained in three minutes, The butter having come, both caps volving dasher, the warm air quickly expelled through the pipe M, and the .butter made hard and readily' separable from the buttermilk.

Having thus described my invention,

I claim as new and desire to secure by Letters Pat` ent- The-combination of hollow revolving arms E E with a hollow flasher-rod, B L, opened at the top to draw in cold air, and 'the outlet-pipe M N, opened at the same time for the discharge of warm air, whereby, after the butter has come, it vmay be suddenly cooled and hardened, as set forth.
